Pedestrian Wind Comfort Studies With a Digital Wind Tunnel Simulator

With the complexity of modern urban areas, pedestrian wind comfort simulations become a critical factor in urban design, helping to ensure the overall well-being, safety, and comfort in pedestrian zones. Predicting and assessing urban wind flow patterns, wind pressure, phenomena like the Venturi effect or the airflow around buildings is an expensive process. Computational fluid dynamics (CFD) simulation helps engineers and urban planners investigate all of these factors early in the design process, before investing in wind tunnel testing.

GPU-based CFD Solver Using LBM

Transient simulations have historically required a high investment of money and time. This GPU-based solver uses the Lattice Boltzmann method (LBM) to tackle this problem by pairing accuracy with unparalleled speed and is accessible via the cloud with SimScale. We partnered with Numeric Systems GmbH to develop this innovative feature through their tool Pacefish®. We have reduced running times for transient simulations like the ones used to test wind comfort from weeks and days to hours and minutes. Its ability to run on multiple GPUs in parallel enables turnaround times that are 20-30 times shorter than standard methods. Moreover, Pacefish® supports several turbulence models such as Smagorinsky, SST-DDES, Hybrid SST-IDDES, and k-omega SST.
